**Materials**
•An Arduino uno or similar.

## **Wirring Up**

![Step 1: Wirring Up](https://content.instructables.com/FND/F50K/I53I5D05/FNDF50KI53I5D05.png?auto=webp&frame=1&fit=bounds&md=70e9b3a2fdf4b99716230979c32b0b29)

1. Put the shield on to the Arduino

2. Wire it up as on the image.

## **Configure the Sketch**

1. Go to [Arduino tweet](https://arduino-tweet.appspot.com/) and get your token

2. Open your sketch

3. Change” token” to your personal token

4. If needed change the ip adress so that it fits your network(Tips: “192, 186, 1, 20” is equal to “192.186.1.20”)

5. Change the text at the end of these to personalise your tweets

char msg0[] = “starting”;

char msg1[] = “something moved”;

char msg2[] = “door open”;

## **Upload and TWEET**

1. UPLOAD the sketch

2. OPEN your serial monitor

3. Send tweet by pressing the switches

## **TROUBLESHOOT**

- If you get error 403 THEN delete all your messages from your TWITTER account and wait a minute

- If you get error 503 THEN re upload and it will get away

- If you get connection failed THEN connect to an other ethernet output or change ip adress
